Holger Rune revisits bad hair day in explaining backwards cap origins at Wimbledon

WATCH: Rune broke down how his ever-affixed backwards hat became an essential part of his on-court ensemble.

Holger Rune went from history to hair-story on Wednesday at Wimbledon, revisiting his infamous no-good-very-bad-hair-day when asked about the origins of his ever-affixed backwards cap.

“I don't know if you remember,” he said after becoming the first Danish man to win a main-draw match at the All England Club since Kenneth Carlsen in 2004, “but when I played my second ATP in Chile, in Santiago, I had some things in the hair. I didn't really like the style myself.”

Then just 17 years old, Rune was overdue for a haircut and opted for a series of hair ties that created a near-Coolio effect during what would be his first career breakthrough.

"It feels good having it like this. So far it's going good, so why not keep it,” Rune told the ATP at the time. “I'm not superstitious in any way, but it's nice because my hair was growing a lot and I thought I don't like playing with [a] hat. So, I did this."

Rune evidently reconsidered—perhaps after seeing pictures of his unorthodox ‘do—and by the end of the year, the backwards cap became a permanent part of the youngster’s on-court ensemble.

“I thought I looked cool with the backwards hat,” he said after defeating George Loffhagen in a rain-impacted first round. “I enjoy to have something on my head. I tried to play without, but then I sweat a lot, so it gets in my eyes and stuff like this.”

Holger’s hat has been on his head through all of his biggest results in the last two years, even indoors when he defeated Novak Djokovic to win the Rolex Paris Masters.

Might the 20-year-old opt for any alternative headgear in the future? Rune has at least one idea.

“Maybe next thing would be a banana,” he offers, though he surely means “bandana.” “Who knows?”
